We always try to bring pieces from our travels to Switzerland. This curious specimen of siderite from the near Goms area is an example. This is a group of rhombohedral siderite crystals that show a curious and unusual curved parallel growth. They are partially covered by calcite and albite, accompanied by brilliant muscovite. From an unusual Swiss locality.
